Specification of Letters Patent.

Application filed November 11, 1919. Serial No. 337,158.

To all whom it may concern:

Be it known that 1, CHARLES S. HORTON,

a citizen of the United States, residing at Huntley, in the county of Yellowstone and State of idontana, have invented new and useful Improvements in llianifold-fleaters, of which the following is a specification.

This invention relates to attachments for internal combustion engines of automobiles and has for its object the provision of a device for heating the intake manifold of the engine whereby to facilitate starting even in very cold weather and whereby the engine may be run even though cold without using an excessive amount of fuel.

An important object is the provision of a device of this character which is formed as a metal shield or shell disposed against and partially embracing the intake manifold, this shell being provided with a hole for the passage of one of the stud bolts holding the arms which secure both the intake and exhaust manifolds upon a very popular type of engine, and the shell being furthermore provided with an apertured ear for the passage of one of the bolts which connect the carbureter flange with the manifold, the shell having its extreme lower portion containing an asbestos wick or pad adapted to be saturated with gasolene which when ignited. will effectually heat the intake manifold.

An additional object is the provision of a device of this character which will be extremely simple and inexpensive in manufacture, which may be readily installed by even an unskilled person, which will be efficient and thorough in operation, durable in service, and a general improvement in the art.

lVith the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings in which Figure 1 is a side elevation showing my device in position,

Fig. 2 is a similar View showing my device in longitudinal section,

Fig. 3 is a cross sectional view on the line 3-3 of Fig. 1,

Fig. 4: is a cross sectional view on the line .l4. of Fig. 1, and

Fig. 5 is a perspective view of my device detached. 1

Referring more particularly to the drawings, the letter A designates the engine of a very popular type of automobile, this engine being provided at one side with exhaust and intake manifolds l3 and C, respectively, and having a carburetor D connected with the intake manifold C by the usual flanges E through which pass bolts F. The letter G designates the stud bolts carrying the arms H which hold the manifolds in place.

In carrying out my invention I provide a shell or shield 10 which is formed from a single piece of sheet metal cut and bent as shown, to provide a body which is substantially U-shaped in cross section throughout the major portion of its length,and including sides 11 and 12 connected by a wall 13. This shell or shield is adapted for disposition upon the intake manifold C in partially embracing relation thereto and the side 11 is provided at its upper end with a hole 14 for the passage of one of the stud bolts G. When the device is in position the lower end thereof extends below the bend in the intake manifold, as clearly shown, and this lower end of the shield or shell is formed as a pan 15 which contains a pad 16 of asbestos or the like retained in position as by means of a trapezoidal yoke 17 mounted within a bearing loop 17 and urged into engagement with the pad by a spring 17". lVhen burnt out, the pad may be easily replaced, as will be obvious. Also formed at the lower portion of the shell is an ear 18 which is apertured for the passage of one of the bolts F.

lVith the device constructed and installed as shown and described, its use is as follows:

When it is desired to start the engine, the operator pours onto the pad 16 a small quantity, such as a tablespoonful or two, of gasolene which he subsequently ignites. The flame from the burning gasolene will rise within the shell 10 and will play upon the intake manifold C, thoroughly heating it so that when the engine is cranked the mixture passing through the intake manifold will be properly heated so that ignition will readily occur in the engine cylinders. It will therefore be seen that the engine may not only be easily started but may be started and run even in very cold weather without any necessity for opening the carburetor adjustment to give a richer mixture.

From the foregoing description and a study of the drawings it will be apparent that I have thus provided a device for the simple and inexpensive in manufacture and installation, but which will very efliciently perform the function for which it is intended.

ferred embodiment of my invention, it is of course to be understood that I reserve the right to .make such changes in the form, construction, and arrangement ofv parts as will not depart from the spirit of the invention or the scope of the subjoined claim. Having thus described my invention, I claim:

An attachment for an internal combustion engine provided with intake and exhaust manifolds secured in place by arms carried by studs, comprising a metallic shield disposed in partially embracing relation to the intake manifold and including side portions, one side portion being provided with a hole 7 for the passage of one of said studs, said While I have shown and described the preshield extending below the intake manifold and having its lower' portion formed as a reservoir, an ear formed at the lower portion of the shield and apertured for the passage of one of the bolts securing theintake manifold to the carbureter flange, and an absorbent pad within said reservoir portion adapted to be saturated with an inflammable liquid. V Intestimony whereof I affix my signature.

CHARLES S. HORTON.-
